We need something not of this world for spiritual combat, but something according to 2 Corinthians 10:4 that is “divinely powerful.” It’s the final piece of spiritual armor from Ephesians 6. It’s the only offensive weapon in the listing. It’s “the sword of the Spirit, which is the word of God” (Eph. 6:17). Since Satan is the “father of lies” (Jn. 8:44) we combat his deception with truth. What is truth? As Jesus said, “Sanctify them in the truth; Your word is truth” (Jn. 17:17). Let me be very clear, following the example of Jesus when He confronted Satan in the wilderness (Mt. 4:1-11), our primary weapon in spiritual warfare is the Bible.
